전동식 워터펌프용 하우징 조립체{Housing assembly for electric water pump}Housing assembly for electric water pump

본 발명은 전동식 워터펌프용 하우징 조립체에 대한 것으로서, 더욱 상세하게는 하우징과 브라켓이 일체로 형성되어 별도의 체결부품을 사용하지 않고 용이하게 조립하여 차체에 워터펌프를 장착할 수 있는 전동식 워터펌프용 하우징 조립체에 대한 것이다. The present invention relates to a housing assembly for an electric water pump, and more particularly, for an electric water pump in which the housing and the bracket are integrally formed so that the water pump can be mounted on the vehicle body by easily assembling it without using a separate fastening part for the housing assembly.

일반적으로, 워터펌프는 엔진의 냉각 및 실내 난방을 위하여 엔진 및 히터에 냉각수를 순환시키기 위한 장치이다. 워터펌프에서 토출된 냉각수는 엔진, 히터, 또는 라디에이터와 열교환을 하며 순환한 후 워터펌프로 다시 유입된다. 이러한 워터펌프는 크게 기계식 워터펌프와 전동식 워터펌프로 나누어 지는데, 엔진 냉각을 최적인 상태에서 컨트롤 하는 것이 가능하고, 엔진 주위의 구조를 간소화하여 차량 연비를 향상시키는 전동식 워터펌프가 널리 사용되고 있다. In general, a water pump is a device for circulating coolant to an engine and a heater for engine cooling and indoor heating. The coolant discharged from the water pump exchanges heat with the engine, heater, or radiator, circulates, and then flows back into the water pump. These water pumps are largely divided into mechanical water pumps and electric water pumps, and electric water pumps that can control engine cooling in an optimal state and improve vehicle fuel efficiency by simplifying the structure around the engine are widely used.

종래에는 워터펌프를 고정하기 위한 브라켓을 하우징의 밑면에 다수의 스크류를 사용하여 고정하고 브라켓의 양측에 절곡된 플랜지에는 방진고무를 결합하여 차체의 마운트에 지지되도록 연결조인트로 마운트에 고정하였다. 또는 장착브라켓과 지지패킹을 결합한 후 그 결합체를 펌프에 결합하고, 이렇게 결합된 펌프를 마운트에 스크류로 고정하였다. 이 경우, 고정 작업이 복잡하고, 일정한 무게를 갖는 펌프를 조정하기가 용이하지 않아 결합이 쉽지 않다는 문제점이 있었다. Conventionally, a bracket for fixing the water pump is fixed to the bottom of the housing by using a plurality of screws, and vibration-proof rubber is coupled to the flanges bent on both sides of the bracket and fixed to the mount with a connecting joint to be supported on the mount of the vehicle body. Alternatively, after combining the mounting bracket and the support packing, the assembly was coupled to the pump, and the coupled pump was fixed to the mount with a screw. In this case, there was a problem in that the fixing operation is complicated, and it is not easy to adjust the pump having a constant weight, so that the coupling is not easy.
